I am 3.5 months into my wait for an AAC Eco9. They are not in production anymore. During my search, Thompson Machine came up as a good budget suppressor. Ti-rant and Osprey are other good choices at a much higher price point. Just factor in that the Thompson suppressors do not include a booster to help cycle recoil based pistols.
People I have talked to who have Surefire suppressors liked them but agree they are very expensive for the performance.
Suppressors are new to my State so I have had little listen time. I was the fourth person in my county to get the CLEO sign off some four months after they were deemed legal.

Due to the reduced recoil energy most handguns need a nielsen device that attaches to the barrel then to the suppressor to get it to run. Any firearm that you want to suppress needs some sort of threading even integral suppressed ones

Same here I applied for a SBR and my CLEO told me this is only the second one they have ever done in the 25 yrs he has been there, the other one was for one of the other officers personal HD shotgun 11 yrs ago . I guess I should feel lucky .

SBR's have not been deemed legal yet. As soon as they are, I'm adding a short AR in 300 Blk to my inventory. Other than that, I could care less about them.
Our NFA legality is by AG opinion. No laws are changing to make them legal. The constitution is very clear, NFA items are illegal unless all Federal requirements are met. Since NFA requirements have to be met to buy one anyway, they should all be legal. A previous AG said only Curios and Relic items qualified. Not sure how he figured that since C&R is not mentioned in the MI constitution. So one opinion at a time, NFA items become acceptable. So far it is AOW, full auto, and suppressors.

The Surefire that i seen used at training a few years back was a DC "direct connect" that attached to the flash hider of the M4. We were outside of an old middle school that we were using for training in the middle of town, the guy fired 3 shots into a mound and it sounded like an air rifle. Another friend of mine had a Sig 5.56 AR with an AAC blackout flash hider on it with an AAC "DC" suppressor. It wasnt "as loud" but to me it was still loud, he wasnt using subsonic ammo.

Air rifle sound from a supersonic bullet?
Surefire may build a good suppressor but at twice the price of AAC in .30 ($1995 vs $1050 MSRP) it is hard for many to justify. And that is for the cheapest Surefire vs an upgraded AAC (7.62SD). Plus the QD flash hiders are 25% more expensive than AAC.
I'm just comparing to AAC as an example. There are many good choices out there that are even cheaper!

Ar15 are gas operated they dont need a nielsen device to cycle. Some of the sound comes back through the gas system its like silencing a revolver there is some leakage in a gas operated gun but not nearly as bad as a revolver.

It removes most of the boom. A lot of the noise you still hear is the crack of the sound barrier breaking and the operation of the action.

Ive got a surefire 308 suppressor in the works since september last year. Should have the stamp soon. I went surefire since the suppressor will eventually ride on a larue 308. I wanted one rated for very heavy use. I also like the surefire muzzle brake ive got one on my savage 10 fcpsr and that damn thing has recoil like a carbine length ar15 now!!

Ive also got a silencerco stainless sparrow 22lr suppressor for my ruger 22/45 that is one disgustingly quiet gun. Someone clapping is louder than that gun.
